Ref; a recent thread advocating the advantages of PEX in relation to
In our case not galvanized pipe. But copper.
Some homes in this area (municipal water supply) of similar age to this
house (36 years) have experienced pinhole leaks in their (generally
half inch) copper plumbing, within the house.
We have not had any problems with such pin holing, although even glass
lined hot water tanks here traditionally do suffer from corrosion and
leakage. We have replaced at least three in some 30+ years and
suppliers will not warranty them for more than three years!
When we refurbished the bathroom within last couple of years we took
the precaution then of replacing any copper that was within a wall.
However all other plumbing is accessible from our unfinished basement.
Just had the thought that our very deeply buried cold water pipe in
from the street is three quarter inch copper! Municipal stop-cock some
six to eight feet down at the street, with the actual connection to the
main at least another six feet below that and our own residential shut
off a couple of feet above basement floor.
We guess we'd never know if the underground developed pinholes or
something more serious until flow seriously decreased or failed?.
BTW. Our water is presently unmetered; whether that will change in
future (climate warming, water shortages, additional growth in the
area) etc. is unknown. And if it did become so the meter due to the
depth of the service pipe would presumably be in the house.
But just to pose the question; suppose it did leak, underground? Is
there any way we could push PEX or some other 'liner' through the three
quarter copper out to the street as a replacement?
Just thinking out loud! Any comment or criticism welcomed.
Seasons greetings to all.
